Dr. Mark Tulchinsky of Pennsylvania State University offers a response in this Second Opinion column.
3D-printed transducer focuses ultrasound waves
October 26, 2016 -- Researchers have found a way to control high-pressure ultrasound to manipulate, move, or destroy structures noninvasively by using 3D-printed laser-generated focused ultrasound transducers, according to a new report in Applied Physics Letters.
3D/4D ultrasound matures as it shows clinical value
October 19, 2016 -- Initially a technology used only by early adopters, 3D/4D ultrasound has indeed come of age, buoyed by mounting evidence of its diagnostic utility in a variety of clinical applications. Today, 3D/4D ultrasound is increasingly being used by healthcare institutions around the world.
China's medical device market shows promise despite slowdown
October 19, 2016 -- The market for medical devices in China still has great potential despite a recent slowdown in the segment's growth rate, according to a new report by China MedTech Marketing (CMTM). In this article, CMTM's Owen Tang explains how a projected decline in the growth rate isn't expected to dampen enthusiasm for medical devices, due to a variety of factors.
Sonographers remain vulnerable to musculoskeletal pain
October 18, 2016 -- Work-related musculoskeletal disorders still remain a bane for sonographers, if a recent survey in Sweden is any indication. However, much can be done to improve sonographer working conditions and decrease the prevalence of pain, researchers reported in a study to be published in the January 2017 issue of Applied Ergonomics.
Contrast US boosts diagnostic power of breast ultrasound
October 6, 2016 -- Contrast-enhanced ultrasound can be an effective method for the differential diagnosis of benign and malignant breast lesions, offering improvements in diagnostic accuracy over conventional breast ultrasound, according to research published in the October issue of the Journal of Ultrasound in Medicine.
Machine learning may aid reading of thyroid ultrasound
September 27, 2016 -- Can machine-learning techniques perform better than a radiologist in differentiating between malignant and thyroid nodules on ultrasound? It depends on the experience level of the radiologist, according to research published in the October issue of the American Journal of Roentgenology.
Contrast US clears up indeterminate HCC cases on MRI
September 22, 2016 -- Contrast-enhanced ultrasound is highly effective for characterizing tumors thought to be hepatocellular carcinoma (HCC) but indeterminate on MRI, according to a presentation at the 2016 Advances in Contrast Ultrasound - Bubble Conference earlier this month in Chicago.
MR/TRUS fusion biopsy targets high-risk prostate cancer
September 20, 2016 -- Targeted prostate biopsies guided by fused MR and transrectal ultrasound (TRUS) images can detect more cases of aggressive prostate cancer than traditional systematic biopsies guided by TRUS alone, according to a multicenter study published recently in Urologic Oncology: Seminars and Original Investigations.
Echo reveals why smoking ups risk of heart failure
September 15, 2016 -- Smokers have thicker heart walls and less heart-pumping ability on echocardiography scans than individuals who don't smoke, factors that increase the risk of heart failure, according to research published September 13 in Circulation: Cardiovascular Imaging.
